RESUMO

The transcriptional activity of a human transposon-like family of repeats, called the THE-1 family, has been studied in cell culture and in human tissue. Both strands of THE-1 are present in several discrete length poly A plus RNAs. Primer extension studies and the structures of cDNA clones show that these THE-1 transcripts are usually the product of other transcription units. The THE-1 LTR provides the polyadenylation processing site for two transcripts, which result from upstream non THE-1 promoters. Yet another transcript, containing an internal THE-1 element in the probable sense orientation, is greatly enriched in a polysomal size fraction.
